Sports board

Abstract

A sports board includes a foam core, a non-foamed plastic plate, and a foam skin. The bottom surface of the foam core has a lower exposed area that is not covered by the non-foamed plastic plate. The top surface of the foam core has an upper exposed area that is not covered by the foam skin. The foam core also has an exposed peripheral area, which is located between the lower exposed area and the upper exposed area.

What is claimed is: 
     
         1 . A sports board comprising:
 a foam core having a bottom surface, a top surface, and an exposed periphery, wherein the bottom surface of the foam core has a lower foundation and a lower exposed area surrounding the lower foundation while the top surface of the foam core has an upper foundation and an upper exposed area surrounding the upper foundation, wherein the exposed periphery of the foam core is located between the lower exposed area and the upper exposed area; and   a non-foamed plastic plate disposed on the lower foundation of the bottom surface of the foam core and covering only the lower foundation.   
     
     
         2 . The sports board as recited in  claim 1 , further comprising a foam skin disposed on the upper foundation of the top surface of the foam core and covering only the upper foundation. 
     
     
         3 . The sports board as recited in  claim 1 , wherein an area of the lower foundation of the bottom surface of the foam core is greater than that of the lower exposed area of the bottom surface of the foam core. 
     
     
         4 . The sports board as recited in  claim 2 , wherein an area of the upper foundation of the top surface of the foam core is greater than that of the upper exposed area of the top surface of the foam core. 
     
     
         5 . The sports board as recited in  claim 1  further comprising a connecting foam layer bonded to the bottom surface of the foam core and covering only the lower foundation, wherein the non-foamed plastic plate is bonded to the connecting foam layer and covers only the connecting foam layer. 
     
     
         6 . The sports board as recited in  claim 5 , wherein the bottom surface of the foam core is flat. 
     
     
         7 . The sports board as recited in  claim 4  wherein the upper foundation of the top surface of the foam core is concaved. 
     
     
         8 . The sports board as recited in  claim 7 , wherein a top surface of the foam skin is higher than the upper exposed area of the top surface of the foam core. 
     
     
         9 . The sports board as recited in  claim 7 , wherein the bottom surface of the foam core is flat. 
     
     
         10 . The sports board as recited in  claim 5 , wherein the foam core is made of expanded polypropylene with color. 
     
     
         11 . The sports board as recited in  claim 10 , wherein the non-foamed plastic plate is made of polypropylene while both of the connecting foam layer and the foam skin are made of expanded polypropylene. 
     
     
         12 . A sports board comprising:
 a foam core having a bottom surface, a top surface, and an exposed periphery, wherein the bottom surface of the foam core has a lower foundation and a lower exposed area surrounding the lower foundation while the top surface of the foam core has an upper foundation and an upper exposed area surrounding the upper foundation, wherein the exposed periphery of the foam core is located between the lower exposed area and the upper exposed area;   a connecting foam layer bonded to the bottom surface of the foam core and covering only the lower foundation;   a non-foamed plastic plate bonded to the connecting foam layer and covers only the connecting foam layer; and   a foam skin disposed on the upper foundation of the top surface of the foam core and covering only the upper foundation.   
     
     
         13 . The sports board as recited in  claim 12 , wherein the upper foundation of the top surface of the foam core is concaved. 
     
     
         14 . The sports board as recited in  claim 13 , wherein a top surface of the foam skin is higher than the upper exposed area of the top surface of the foam core. 
     
     
         15 . The sports board as recited in  claim 14 , wherein the bottom surface of the foam core is flat. 
     
     
         16 . The sports board as recited in  claim 15 , wherein the non-foamed plastic plate is made of polypropylene while both of the connecting foam layer and the foam skin are made of expanded polypropylene. 
     
     
         17 . The sports board as recited in  claim 16 , wherein the foam core is made of expanded polypropylene with color.
